What to Do

Try to spin the eggs on a hard surface. Be careful they don’t slide off and break on the floor!

The boiled egg is the one that spins the fastest.

What’s Happening?

The raw egg is liquid inside so when you try to spin it the liquid sloshes around and slows the egg down. The boiled egg is hard inside so it should spin much faster.

Now try to spin the two bottles. The bottle of ice is just like the boiled egg while the bottle of water is like the raw egg - the water sloshing around inside slows it down so it won’t spin very well.
